i just found a dead bird laying outside my patio door, it is laying on the track for the sliding door, immediately outside the door. It appears to be uninjured and i have no pets and there are no pets in my area. It is laying with its feet up just like it fell over dead there. I also do not have any marks on my door where it would have hit it. Does anyone know what the symbolism is behind this?
